The USGS recently released US Topo maps for Wisconsin, Iowa and Kansas which were the first set of states to feature TIGER data. The TIGER database contains all geographic features — such as roads (more than 6.3 million miles), railroads, rivers, and legal and statistical geographic boundaries — needed to support the Census Bureau’s data collection and dissemination programs.
